Scenario:

Problem:

When opening the Skype for Business client you get in bottom right corner an exclamation mark, for around 10/15 minutes, with the following error: “Outlook Integration Error“.

You open the “Configuration Information“, and you see the MAPI and EWS with OK status.

All Free/Busy features are working fine, no problems are reported.

After waiting around 10/15 minutes, the exclamation mark disappear from the Skype for Business client and everything remains working.

The root cause for this problem, is that the client tries to create the “Skype for Business Contacts” folder in the user exchange mailbox and fails.

This problem only affects users with mailboxes hosted in Exchange Server 2010 with Skype for Business client April 2017 update (or higher). This update deprecates the “Skype for Business Contacts” folder in Outlook and Outlook Web App.
